OIL-TREATING` MIXER.

Application filed. December 27, 1921.

Be it known that I, Manx Banorrnn, a citizen oi' the United States, residing at llest Columbia., Brazoria County. Texas. have invented a certain new and useful Improvement in Oil-Treating Mixers, ofwhich the following is a iulh clear, and exact description. such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to liquid mixers particularly adapted for thefmixing of difterent grades o1C oil or the mixing` with crude oilo'l' ingredients designed to clear or` purify it. otforeign constituents such as basic sediment, water7 etc.

In the apparatusnow commonly used forr mixing such liquids, long; strings oi'pipe are employed andthe oil and purifying ingredicnts are 'forced ,by pump pressure through the long passage thus .provided in such manner that an intimate mixture will iinally result. This method necessitates a large amount oi pipe and a place to lay the pipe. Furthermore the oil, which. is Acommonly heated, is cooled greatly in its passage through the pipe.

An object of my invention is to provide a mixer which will thoroughly mix the oil with the other liquids in a comparatively small space7 thus necessitatingonly a small installation.

Another object is to provide a mixer which is simple and strong in construction and economical to use. Other objects and advantages will be apparent to one skilled in the art after the device is more clearly understood.

Referring to the drawings herewith wherein like numerals ot reference are applied to like parts in all the views: Fig. l is a central longitudinal section through a length of pipe, my mixing apparatus therein being partly in elevation. Fig. 2 is a transverse section on line Q2 of Fig. l. Figure 3 is a broken section on line 3--3 of Fig. 2.

In designing my improved mixer I have contemplated using an ordinary length of pipe l. This pipe is threaded at 2 at both ends thereof for coupling of the same with* in an ordinary string of pipe. It is also threaded internally at 3, at each end to accommodate a bearing plug e, adapted to be Specificationof Letters Ratent.

screwed within the threadedfportion. Each oi these bearingyplugs is of similar lconstruction, and` one only need be described. It.

. my mixingy device theA bearing plugs` t are perforated4 by a plurality of openings 9.

These openings are directed in a. somewhaty spirall direction atan angle inclined tothe central axis ofthe pipe 1. Thisangle is .so arranged as to direct the yfluid` in the proper directionagainst thev mixing device. These openings may be or any number or size sufficient to permit the How of the required amount ot' liquid through the mixer.

The mixing member comprises a longitudinal shaft hai/'ing agitating blades k10 at each end thereof. These blades are intended to cause a rotating motion of the iiuid and of the agitating means. They may be of any ordinary form7 and I have shown inthe drawing one spirally arranged blade at each end of the mixing member. It will be noted that both of these blades have the same formation so that the passage of the fluid will cause a rotative effect in the same direction at each end of the mixer.

Between the two blades l0, I contemplate providing a further device for more thoroughly bea-ting up and mixing the liquid flowing through the device. For this purpose I have formed a central cylindrical shaft 111 having keyed thereto at l2 a sleeve, 13. This sleeve has thereon a series of radially extending bristles 14 forming a brush. As will be apparent, these bristles will be caused to rotate with the blades 10 and thereby assist in thoroughly mixing and agitating the fluid.

In the operation oit my device the oil to be treated will be pumped from the pit though the pipe l which houses my agitator, to the settling tank where the ingredients of t-he oil are adapted to separate. As the oil, with the ingredients mingled therein, are forced by the pumps through my agitator, the flow is given a whirling` motion by the direction of the passages 9 in the bearing plugs. This whirling is in the proper direction to impart a rotative movement to the blades l0. The flow of the fluid along the said blades will further carry outthis rotative movementand will cause the mixer to revolve rapidly. As the fluid passes along the blades and past the agitating brush 14, the ingredients will be thoroughly and intimately mixed. rfhis mixture will be facilitated by the passage of the fluid through the smallL openings 9 in the plugs. Therefore, when the fluid issues from the agitator the different ingredients will be ready for discharging into the separating or settling tank. A

vThe advantages of this type of construction overvthe usual pipeline mixer will be apparent to one skilled in the art, withoutl further description.

vWhat I claim isV new and desire to protect by Letters Patent is:

l. In a device of the character described, a length of pipe, a bearing member in each end thereof, a mixing member in said pipe, having its ends journalled in saidl bearing members, spirally arranged agitating blades on said mixing member, and a brush intermediate the ends thereof, said bearing memblades at an angle to the axis of said cham-' ber.

3. In a device of the character described,

a tubular chamber, a rotatable mixing member journalled for rotation therein, spirally` arranged. agitating blades on said member, and agitating brushes between said blades, said mixing member being adapted for rota` tion by the passage of fluidthrough said chamber.

there- 4. In aV device of the character described,

a tubular chamber, a mixing member, perforated bearing plugs at each end of said `chamber for said member, a spirallyV arranged blade at each end of said member and a brush on said member between said blades.

In testimony whereof, I hereunto affix my4 signature, this the 19 day of December, A. D. 1921. v
